Watch: Obama To Face Tough Questions In Year-End Conference

Jim Bourg / Associated Press

President Barack Obama is expected to face questions about claims of Russian interference in the U.S. election and about the fall of Aleppo in Syria when he holds his year-end news conference Friday.

Obama will take questions from reporters at the White House before leaving for his annual family vacation in Hawaii.

Obama is under pressure to say how the U.S. might be retaliating for Russian hacking that the White House says helped President-elect Donald Trump’s campaign and hurt Hillary Clinton’s. The White House and Trump’s team have been squabbling over the issue, and Trump has dismissed the U.S. intelligence community’s assessment of Russian involvement.
